SHEARS.

Specification of Letters Patent. Patented N 23 1920 Application filed March 1, 1919. Serial No. 279,946.

of the shears, the end in view being to provide pins, which as distinct elements, may be mounted in the nut, and in a sleeve which forms a pivotal connection between the blades of the shears, to prevent relative rotation between the sleeve and the nut while the bolt which engages the nut is being tightened up.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

lVith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in plan, a pair of shears constructed in accordance with the inven-' tion; Fig. 2 is a section on the line 22 of Fig. 1; F ig. 3 is a section on the line 3-3 of Fig. 2; Fig. 4; is a plan of the nut; and Fig. 5 is a section corresponding to Fig. 2 but disclosing a modification.

Referring to Figs. 1 to 4, both inclusive, there is shown a pair of shears comprising a blade 1 and a blade 2, the blade 2 having an opening 3, and the blade 1 having an opening 4. A tubular sleeve 5 is mounted in the openings 3 and 4 and is supplied in one end with seats 6. A bolt 7 passes through the sleeve 6 and includes a head 8 cotiperating with the blade 2, the blade 8 having a screw driver kerf 9. The numeral 10 marks a nut having seats 11 wherein the outer ends of pins 12 are fixed, the inner ends of the pins being adapted to be received in the seats 6 of the sleeve v In practical operation, the pins 12, which are carried by the nut 10, are received in the seats 6 of the sleeve 5, the bolt 7 is passed through the sleeve 5 and the bolt is threaded into the nut-10, the nut being held against rotation, by means of the pins 12, until the bolt is rotated so that its head Scotiperateswith one end of the sleeve 5 and with the outer surface of the blade 2, the nut 10 being drawn down upon the blade 1. In this connection it is to be observed that, as indicated at 14, one end of the sleeve 5 is spaced from the outer surface of the blade 1, so that the bolt can be tightened up any desired degree in the nut 10 without engaging the adjacent end of the sleeve 5.

The construction of the device is such that the pins 12 may be fashioned as elements independent of the sleeve 5 and the nut 10, and be fixed in the nut.

In Fig. 5 of the drawings, a modified form of the invention has been shown. In the said figure, parts hereinbefore described have been designated by numerals previously used, with the suffix a. In this form of the invention, the pins 12 are seated fixedly in the recesses of the sleeve 5" and are received removably in the recesses or seats 11 of the nut 10 Having thus described the invention,what is claimed is A pair of shears including blades; cooperating elements comprising a tubular sleeve forming a pivotal connection between the blades, and a nut at one end of the sleeve and coacting with one blade; a bolt extended through the sleeve, the bolt and the nut having continuous coacting threads, thebolt having a head coacting with the other blade, both of said cooperating elements having seats spaced respectively from the bore of the sleeve and from the bolt-receiving opening of the nut, whereby the threads may be continuous as aforesaid; and pins fixed in the seats of one of co6perating elements and received removably in the seats of the other of said cooperating elements.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
